Video digital monitor and control system and method in use for 3G mobile communication

Abstract

The invention comprises the following steps: connecting a 3G video call to a mobile video media monitoring platform; transmitting the 3G video call to an IP address and port appointed by the platform through RTP protocol and its equipment; when user makes a 3G video call, the system will display the sources of the video signal on an optional menu in term of the authority of the user in order to provide a selection for user; after user selects a source of video signals, the relevant video signals will can be played.

Description

technical field [0001] The invention relates to the field of 3G (third generation mobile communication technology) mobile communication technology, in particular to a system and method for video surveillance using video and voice channels in the 3G mobile communication network. Background technique [0002] With the development of mobile communication technology and digital compression technology, digital video monitoring equipment is gradually widely used in transportation, public security, production management and other industries due to its convenient application, intuitionistic and faithful recording of content information. It is an important means of security prevention and management in public places or areas such as transportation, commerce, electricity, customs, airport stations and even residences. [0003] The more traditional technical method is to place one or more cameras in the above-mentioned application places for on-site shooting, and then transmit the acqu...

Problems solved by technology

[0005] In the prior art, the mobile phone video image monitoring technology is carried out through mobile communication terminals. One is based on the short message (SMS) transmission system for video monitoring, which utilizes the characteristics of less image signal loss and clear and accurate transmission of short message, but it cannot be real-time. Transmission of video images, for example, the technical solution disclosed in the invention "Digital Mobile Phone Transceiver Monitoring Device" with the Chinese authorized announcement number CN 2481096Y and the announcement date of March 6, 2002; the other is based on GSM / GPRS digital communication transmission Network for real-time monitoring of video and image monitoring, but it is not designed for 3G communication networks, and it cannot independently set up monitoring, and must install corresponding decoding software and complex interface equipment. For example, the Chinese authorized announcement number is CN 2724334Y, and the announcement date is The technical solution disclosed in the utility model "Mobile Video Image Monitoring Device" dated September 7, 2005

[0006] Although the above methods can realize digital video surveillance, they either cannot meet the requirements of timely signal transmission, or the system access and compatible technologies are complicated, the software installation is not easy to operate, and the demand for wireless resource bandwidth is relatively high.
